Symptoms
Memory module SEEPROM data is no longer populated with an Oracle Part Number, instead a generic string is written to the Serial Presence Detect (SPD) data on the DIMM which can be misinterpreted to be a FRU PN.

fru_part_number contains two fields - the first field (07075400 using the above example) has traditionally been used for the Oracle Part Number, however with DDR4 DIMMs this is no longer the case and 07075400 is NOT a valid Part Number and should not be used for determining the model of DIMM installed.
